TECHNICAL FIELD

The present invention relates to a heat insulation and support structurebetween a moving window (sliding window) and a fixed window constitutinga sliding window system, or between a moving window and another movingwindow. More particularly, the present invention relates to a windowchassis insulating structure and a glass panel supporting (mounting)structure in a center bar portion in which a window chassis of a movablewindow and a fixed window (or other movable window) overlap each otherwhen a sliding window of a two-side supporting frame window having atwo-sided supporting frame for supporting only both sides of a glasswindow constituting a sliding window system, is closed,

BACKGROUND ART

In general, when a sliding window (moving window) and a fixed window offour-side supporting frame window type that support the four sides ofthe glass window with thick supporting frames as a movable window(sliding window) and a fixed window constituting a sliding window systemare used (FIG. 1a ), as shown in a-a′ cross-sectional view (longitudinalcross-sectional view) of FIG. 1b , the sliding window system has astructure in which a roller slides along a roller guide rail on achassis frame 1 by providing the roller installed on a lower part of awindow chassis 2 a in which a glass is fitted. However, in case of afour-side supporting frame window type, as shown in the b-b′cross-sectional view (cross-sectional view) of FIG. 1 b, there was nogreat difficulty in achieving both solid glass supporting function andgood thermal insulating function through a shape and a structure of aportion where the glass (glass panel) is inserted and fixed and a thick(80-100 mm) center bar portion of the window chassis 2 a that canprovides insulating and sealing function as well as glass supportingfunction when the sliding window (moving window) and the fixed windoware overlapped.

However, in recent years, as the openness of windows is emphasized, atwo-side supporting frame window type sliding window (refer to FIG. 2a )supporting only both sides of a glass window constituting a slidingwindow is increasingly used. In an example of this two-side supportframe window type sliding window (example of Schueco's product inGermany), a two-sided window chassis 2 b into which a glass 2 g isfitted exists only on both sides of the glass 2 g, and moreover for wideopenness, the two-sided window chassis 2 b should have a narrow chassiswidth of about 40 mm. And as shown in the cross-sectional view of the[a-a′] line in FIG. 2b , under the glass 2 g, a lower glass supportinsulation brackets 2 p as a member (organic product such as polyamideor PVC) that wraps the glass end for the purpose of preventing damage,buffering, and insulation without an aluminum chassis, is provided. As aroller 2 r is directly coupled to the lower glass support insulationbracket 2 p, the sliding window of the two-side support frame windowtype has a structure in which the roller 2 r slides along the rollerguide rail on the window frame 1. In addition, as shown in the b-b′cross-sectional view of the open state of FIG. 2c and the b-b′cross-sectional view of the closed state of FIG. 2d and the enlargedview of the main parts, among a thin side chassis parts 2 b 1 and 2 b 2provided in the inner and outer surfaces to support a glass side supportinsulation bracket 2 gb attached to and coupled to the side of the glass2 g, an aluminum metal outer cap 2 b 1 which has relatively excellentholding force, should not extend to the overlapping (closed state)portion CN of the sliding window in order to improve thermal insulationperformance. (When aluminum is formed in a ‘⊂’ shape, a heat transferpath is connected from the inside to the outside, resulting in rapidheat loss, which leads to a problem in that energy efficiency is reducedand therefore surface condensation of water is induced.) On the otherhand, a synthetic resin (or carbon fiber) inner cap 2 b 2 and the glassside support insulation bracket 2 gb are arranged adjacent to each otherto form a center bar portion. Here, mohair for wind/dust protection orexternal and internal elastic gaskets (g-out, g-in in FIG. 2d ) forinsulation are symmetrically installed and provide a windproofstructure.

Thanks to this structure, it is possible to achieve a certain level ofthermal insulation performance, however, when the sliding window isclosed, the force holding the glass (2 g) in the overlapping portion(CN) is weak. As a result, there is a problem of exposing structuralweakness that excessive deformation occurs in the glass side supportinsulation bracket 2 gb made of synthetic resin in an environment wherestrong wind acts on the glass.

On the other hand, as an example of a sliding window of another two-sidesupporting frame window type (refer to FIG. 2a ) having a structuredifferent from the structure described above, in the example shown inFIGS. 3a to 3d (Example of Sky-frame's product in Switzerland), a windowchassis 2 b into which a glass 2 g is fitted exists only on both sidesof the glass 2 g, and there is no aluminum chassis under the glass 2 gas shown in the cross-sectional view of the line [a-a′] of FIG. 3a . Inaddition, as shown in the b-b′ cross-sectional view of the open state ofthe general window of FIG. 3b and the double-opening window of FIG. 3c ,and the b-b′ cross-sectional view and enlarged view of the closed stateof the double-opening window of FIG. 3d , among a thin side chassisparts 2 b 1 and 2 b 2 provided to support a glass side supportinsulation bracket 2 gb attached and coupled to the side surfaces of theglass 2 g from the side, an aluminum metal outer cap 2 b 1 does notextend to the overlapping (closed) portion (CN) of the sliding windowfor improved insulation performance, and only a synthetic resin innercap 2 b 2 and the glass side support insulation bracket 2 gb aredisposed adjacent to each other in the closed state. However, in orderto solve the problem of insufficient rigidity (excessive deformation)according to the properties of the material of the synthetic resin innercap in the overlapping portion CN when the sliding window is closed, inthe state where the assembly of the glass 2 g is completed, another cap2 gc being inserted into the gap portion between synthetic resin innercap 2 b 2 and the glass side support insulation bracket 2 gb in a wedgeshape so that there is no loose gap between them, is additionallyprovided.

However, before the assembly of the glass 2 g is completed, as shown inFIG. 3d of the accompanying drawings, in the process of coupling thesynthetic resin inner cap 2 b 2 into the aluminum metal outer cap 2 b 1,as shown in FIG. 3d , they must be interconnected through a rollercompression processing process. At this time, due to a protruding outerstepped portion 2 b 1 a of the aluminum metal outer cap 2 b 1, it isdifficult to draw into the roller, so that processing thereof isdifficult. Furthermore, it is possible to achieve a certain level ofrigidity increase performance, but due to the high deformability andplasticity of the synthetic resin inner cap 2 b 2, there is a problem inthat structural weaknesses due to large deformation occurring in thesynthetic resin inner cap 2 b 2 and the glass side support insulationbracket 2 gb made of synthetic resin cannot be completely eliminated inthe environments where strong winds act on the glass. This situationoccurs because the force itself that holds the glass 2 g from the sideat the overlapping portion CN when the sliding window is closed is notincreased.

As an example of a sliding window (refer to FIG. 2a ) of a two-sidesupport frame window type of another structure, in the example shown inFIGS. 4a to 4c (an example of a product manufactured by ‘Panoramah’ ofSwitzerland), the material of an inner cap 2 b 2 that supports, from theinside, a glass side support insulation bracket 2 gb corresponding tothe portion holding the glass 2 g from the side in the overlappingportion (CN) when the sliding window is closed, is also a soft syntheticresin material. Therefore, it has structural weaknesses in the samemeaning.

Technical Problem

The present invention is to solve the problems of the prior invention ofthe applicant of the present application described above. It is atechnical problem of the present invention to provide a speciallyimproved structure for the component corresponding to the inner cap 2 b2 in the prior art so as to control the deformation of the glass sidesupport insulation bracket 2 gb in a window type sliding window with atwo-side supporting frame that supports only both sides of the glasswindow constituting the sliding window, in order to maintain goodthermal insulation function and to secure better glass panel fixingfunction in constituting a narrow window chassis 2 b that exists only onboth sides of the glass 2 g, even if a structure is adopted that thealuminum metal outer cap 2 b 1, which has relatively excellent fixingsupport, does not extend to the portion CN where the sliding windowoverlaps (when closed) in order to improve its thermal insulationperformance, among the thin side chassis parts 2 b 1 and 2 b 2 providedto support the glass side support insulation bracket 2 gb attached toand coupled to the side surface of the glass 2 g from the inner andouter surfaces.

The finishing work is completed by additionally extending andproviding foam rubber insulating gaskets 11 e and 21 e between thesecond protruding side support ends 11 c 2 and 21 c 2 and the glasspanels 10 g and 20 g. Thereby, the rotation of the rigid support members11 c, 21 c in a direction opposite to the direction of the arrow in FIG.6d (rotation in the opposite direction to the rotation prevented in FIG.6d ) is also controlled and prevented by the assembled glass panels 10g, 20 g and the glass supporting insulation brackets 10 a, 20 a, thestability of the entire device can be further supplemented andmaintained.

In the above, while describing in detail a preferred embodiment of thepresent invention is applied to window having a pair of glass in which aplurality of glass panels 10 g, 20 g are formed by overlapping eachother by bonding with a predetermined interval and a sealing memberthere between to realize a vacuum in the gap.
